IMPROVEMENT IN TRAc'riON-WHEELS.

Specification forming part of Letters Patent N0. 139,711, dated June 10, 1873 application led March 8, 1873.

To all whom it may concern:

Beit known that I, JOHN G. GALLET, ot' St. Augustine, in the county of Knox and State of Illinois, have invented a new and useful Improvement in Elastic Wheel for Road-Steamers, of which the following is a sprcilication:

In the accompanying drawing, Figure 1 is a side elevation of my improved elastic wheel. Fig. 2 is a side view of the same, partly in section,on the line c c, Fig. 1; and Fig.3 shows hin ge-connection of guard-plate with side bolts.

Similar letters of reference indicate correspondin g parts.

The invention consists in the improvement of means for holding the rubber sections of a tire on the wheel, so that they will be held securely and yet be easily detachable.

In the drawing, A is the solid plate or spoke wheel, of suitable metal, being provided with two projectix g rims, a and b. The outer rim, b, may be hanged to keep the rubber'in'place. The rubber tire B may be of two or more pieces, placed around the periphery ofthe wheel. Any part ot' tire B may easily be replaced, if it should be required. Rubber tire B is firmly sustained on the wheels by guard-plates C, which are arranged at suitable distances from each other. Plates C, of rectangular shape, have applied, perpendicularly to them and in the radial direction of the wheel, side bolts d, which pass through suitable holes in rims a and b, and are rmly secured to the latter by means of metal and rubber washers e and pins or nuts f. The side bolts d may also be hinged to plate C, or eonnected by ball-and-socket arrangement, so

that the wheel may pass projecting objects on` plates, forming, instead of a polygonal, an al-A most circular, periphery, avoiding thereby, in

connection with the elastic washers, the noisy concussion ot the old wheels. The breaking strain of the rubber tire is, by means Ot the strong support of the guard-plates, obviated, and the elastic material applied so as to give bearing-surface and spring-action against concussion.

Having thus described my invent-ion, I

claim as new and desire to secure by Letters Patent- The combination, on a solid plate, A, of two rims, a b, the plates O, hinged bolts d. elastic washers eand pins f, to hold the sectional rubber blocks ot' a wheeltire, in themanner described. v
